LATRINE.

Specification of Letters Patent.

Patented Apr. 14, 1914.

Application filed August 19, 1912. Serial No. 715,912.

citizen of the United States, residing at Marietta, in the county of Washington and State of Ohio, have invented a new and useful Latrine, of which the following is a specification.

The present invention relates to improvements in latrines, and more particularly to latrines for use in the field or in camp by troops in active service or by camping parties, the primary object of the invention being the provision of a novel form of means actuated by the seat, when occupied, to inject into the main hopper a predetermined supply of disinfectant, thus producing a sanitary latrine.

VVit-h the foregoing and other objects in view which will appear as the description.

proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a perspective view of the complete latrine. Fig. 2 is a side elevation thereof, the hopper and disinfectant casing being shown in vertical section with the valve in open position. Fig. 3 is an enlarged section of the lower end of the valve stem and disks and adjacent portion of tank and charge cup.

Referring to the drawings, the numeral 1 designates the hopper, whose lower end, when in the proper position, is below the surface of the ground, the same being properly shaped so that the receptacle or hopper may be readily emptied and cleaned when necessary.

Connected to and supported at the forward side near the top of the hopper 1 is the liquid disinfectant carrying chamber or reservoir 2 which is provided with the removably capped filling spout or conduit 3 and with the valve supporting cylindrical or tubular chamber 4 having inlet apertures 5 at its lower end. Concentric of this chamber at and in the bottom of the tank 2 is an outlet aperture 5 which conducts the liquid disinfectant into the charge cup 6, said charge cup 6 being provided with the outlet aperture 7 and forming communication to deliver the disinfectant into the discharge spout 8 which leads through the aperture 9 into the hopper 1 intermediate of the length of the same.

A valve stem 10 is disposed concentrically of the tube 4: and extends upwardly out of the top of the casing 2 through the seat car rying board 12 through the aperture 11, the upper end a of the said rod being disposed to be depressed by the seat 13 when occupied, said seat 13 being provided with the usual cover or lid 14:.

Upon the stem 10 within the chamber 2 is mounted a coiled spring 15 which normally holds the stem 10 elevated with the upper valve disk 16 seated within the lower end of the tube at and the closing valve 17 disposed upon the under surface of the charge cup 6 so as to seal the outlet aperture 7, the outlet apertures 5 being open at all times so that the liquid disinfectant is permitted to flow within the charge cup 6 and under normal conditions being retained therein by the lower valve disk 17.

By means of the detachable legs 18, the platform 12 is properlysupported in any convenient manner and the same may be detached so as to permit of the ready knockdown of the latrine for shipment.

From the foregoing description, taken in connection with the drawings, it is evident that when the seat 13 is unoccupied, that the disk 17 will seal the aperture 7 so that the predetermined charge within the charge cup 6 will be properly held in suspense to be ejected from the charge cup upon the occupancy of the seat 13 and the depression of the stem 10, such depression of the stem moving the valve 17 to permit the disinfectant to flow from the charge cup into to close the aperture 5 and thus not permit an additional amount of the disinfectant to flow.

What is claimed is:

In a latrine, the combination with a hinged seat and a soil hopper having an opening in one wall, of a disinfecting device, including a tank having an outlet port in its bottom, a ported cup depending from the under side of the bottom with its port in axial alinement with the port of the tank, a removed discharge spout below and incasing the bottom of the tank and discharging into the opening of the hopper, a cylindrical tube disposed in the tank with its ends abutting the top and bottom of the tank, its lower end surround the spout 8, while the disk 16 will be seated ing the outlet port of the tank and being provided with a plurality of ports in its walls at a point slightly above the bottom of the tank, a spring elevated stem extending through the cup, bottom and top of the tank and concentrically of the tube, the upper end of the stem being disposed to engage the seat to be depressed by the seat, and two disk valves fast to the stem, one disk valve being upon the lower end for movement to and from the lower side of the cup to control its l port and the other for movement in the lower end of the tube to and from the bottom 7 of the tank, to control the. outletport of the tank and the ports of the tube.

In testimony that I claim the foregoing as my own, I have hereto atlixed my signature in the presence of two witnesses.
